7 Claims. (Cl. 81.--71) This invention relates to wrench devices employing a plurality of wrench elements of different sizes to fit correspondingly different size sockets of screwsor other devices in the operation of tightening and loosening such devices. 7

More particularly, the invention deals with what we term a turret head type of wrench, wherein the turret head is adjustable with respect to a body and retained in different positions of adjustment with respect. to said body in bringing the various wrench or tool elements in operative position.

Still more particularly, the invention deals with a tool of the character described employing a friction coupling between the head and body to provide yielding of the head in certain uses of the tool.

The novel features of 'the invention will be best understood from the following description, .when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed and, in which, the separate partsare designated-by suitable reference characters in each of the views-and,' in-which:

Fig. 1 isa side viewofattoolnmade according toour invention; and

Fig. 2 is an enlarged sectional view through the .tool shown in Fig. 1.

In practice, we provide a body 10, to which is fixed a tool handle member 11, preferably of hexagon crosssectional form and which represents the largest size tool of the tool combination disclosed. The handle 11 extends substantially at right angles to the surface 12 of the body 10.

The body has a 45 extending side portion 13 with a socket therein defined by a bottom wall 14 at 45 to the handle 11 and a conical wall 15, which is 135 to the wall 14.

The socket has, centrally of the wall 14, a threaded bore 15 adapted to receive a threaded end 17 of a clamping nut or screw 18. The nut or screw 18 has an unthreaded enlarged shank 19, forming a pivot member, on which a turret head 20 is rotatably mounted. The outer end of the nut or screw 18 has an enlarged collar portion 21, which is adapted to seat upon a washer 22 at the outer surface of the head 20 and integral with the collar is an enlarged wing-type fingerpiece 23, by means of which the head 20 may be clamped into fixed or adjusted position with respect to the body 10.

The head has inner and outer bevelled or conical surfaces 24 and 25 disposed at right angles to each other. The conical surface 24 parallels the wall 15 of the body socket and has an annular recess 26, in which a ring of yieldable friction material 27 is mounted and secured.

Embedded in the head 20 and spaced circumferentially around and protruding from the outer bevelled or conical surface 25 are a plurality of tool or wrench elements 28, these elements being of hexagon cross-sectional form and of different sizes, ranging from a small to a large size, the large size, however, being smaller than the size of the 2,753,745 Patented July 10, 1956 tool handle 11. The elements 28.are fixedly secured'and keyed to the head '20 and are adapted to be brought into position, as noted by the element 28' in Figahof the drawing, whichpos'ition would .be the use or operative position of the element inengaging a screw or nut in the operation of tightening or loosening the same. y In this connection, it will be understood that sidewalls of the body 10 are rounded, conforming to the contour of. "the head 26 and one of these side walls .is designated by 'the reference character 29 in Fig. l of the drawing. This rounding of the body 10 facilitates positioning of the tool in a corner or confined area, jwh'lere a nut 'or screw requires tightening or loosening.

In the use of the tool, the, winged nut 18 is loosened and the head 20 is adjusted to bring the desired element 28 into the operativeposition noted at 28', after which, the nut is tightened and this tightening can be accomplished to extend a positive gripp ing engagement between the head 20 and body 10 or the tightening maybe nominal, so as to provide a yieldable frictional engagement, so regulated as to provide yielding movement of the head 26), after a screw, nut or the like has been tightened to a predetermined degree. This is desirable in certain adaptations and uses of screws in materials which are subjected to breakage or rupture, in the event that the screw or other device is tightened. to an excessive degree.

It will also be apparent thatthe handle tool element 11 can alsobe utilized in tightening or loosening threaded members of anykind, in which latter instance the body 10 is used as a handle member. In all other instances, the handle member 11 is utilized in the operation of the tool.

Having fully described our invention, what we claim as newand desire to secure by Letters Patent is:

1. An adjustable turret head tool, comprising a; body having a handle member protruding therefrom, the body having an extension atone side thereof substantially at right angles to the handle member, a turret head adjusb ably mounted in connection with said extension on a pivot member having an axis arranged at 45 to the axis of said handle member, said turret head having a plurality of circumferentially spaced tool elements of different sizes the axis of each of which is 45 to the axis of said pivot member, said elements being selectively brought into operative position with respect to said body, the tool element, when in operative position with respect to the body, being disposed at right angles to said handle member, and means including said pivot member for securing the head in fixed position with respect to said body.

2. An adjustable turret head tool, comprising a body having a handle member protruding therefrom, the body having an extension at one side thereof substantially at right angles to the handle member, a turret head adjustably mounted in connection with said extension on a pivot member having an axis arranged at 45 to the axis of said handle member, said turret head having a plu rality of circumferentially spaced tool elements of different sizes the axis of each of which is 45 to the axis of said pivot member, said elements being selectively brought into operative position with respect to said body, the tool element, when in operative position with respect to the body, being disposed at right angles to said handle member, means including said pivot member for securing the head in fixed position with respect to said body, and said handle member being of hexagonal crosssectional form and protruding from the body beyond the limits of the tool elements of said head.
